GUNDRILL · SINGLE LIP GUNDRILL
Our brazed gundrills are single-lip gundrills made to order in diameter, overall length, drilling depth, shank, coating and chip breaker. Standard tools cover Ø3.00–33.02 mm with hole tolerance IT9 and surface roughness 0.1–3.0 µm; we also make special gundrills.
FEATURES
Features of the standard and SF types, as listed in the gundrill catalogue.
A general-purpose design suits a wide range of working conditions; the simple construction gives high strength and relatively low manufacturing and replacement costs. For carbon steel, alloy steel, cast iron and non-ferrous metals.
Designed for better chip evacuation, it is efficient at high cutting speeds and suits hardened alloys, stainless steel, titanium, nickel alloys and heat-resistant alloys.
Made to your specified diameter, overall length, drilling depth, shank, coating and chip breaker.
Used in the automotive, aerospace, medical device, mould & tool making and oil & gas industries.

GUNDRILL LINE-UP
From Ø10 we use the indexable 600 series; smaller diameters and special shapes are made as brazed gundrills.
Tell us the diameter, overall length, drilling depth, workpiece material and machine, and we will confirm whether we can make it and propose specifications.
